325W Stereo High Performance, High Definition, Class D Amplifier 'TPA3255'
The TPA3255 is a high-performance Class-D power amplifier that achieves the best sound quality with Class-D efficiency. It features an advanced integrated feedback design and a unique high-speed gate driver error correction function (PurePath Ultra-HD). This technology provides excellent audio quality with very low distortion across the entire audio band. Additionally, it achieves high power efficiency and very low idle loss of just 2.5W in the power stage. These are accomplished by using 85mΩ MOSFETs and an optimized gate driver scheme, resulting in idle losses that are significantly lower than standard discrete implementations. 【Features】 ■ Differential analog input ■ Total output power at 10% THD+N ■ Total output power at 1% THD+N ■ Advanced integrated feedback design ■ High-speed gate driver error correction ■ Multiple configurations available: Stereo, Mono, 2.1, 4xSE *For more details, please contact us.
